EXCLUSIVE: US expands intel, targeting support for Saudi campaign against Iranian ally

More than 100 US military advisers are on the ground in Saudi Arabia providing intelligence and targeting support to the Kingdom in its military campaign against the Iran-backed Houthis in Yemen, multiple sources familiar with the effort say. The assistance comes as fighting on the peninsula intensifies and risks spilling into open war with the Houthis, threatening a second major shipping corridor out of the Middle East. The US military personnel are working as part of a newly-established joint forces command, which was formed in recent weeks amid signs Iran was ramping up its own efforts to aid Houthi attacks against Saudi Arabia, one of the sources, a US official, said. That official put the total at roughly 200 troops. The presence of US troops assisting Saudi Arabia was described to CNN by five sources familiar with the operations.
